A tip for wells with their hands, the device and installation rules

Proper arrangement of wells is not possible without the necessary site – tip. Installation tip on the hole not only protects the structure from falling into it of foreign objects, but also greatly facilitates operation of the well supply system. Some people are of the opinion that installation tip: additional expenses: the wellhead can wrap film or adhesive tape, and the design to cover the old capacity. This view is mistaken, since the film or tape will not be able to defend well in the case of groundwater rise that may lead to system destruction and water pollution.

Basic functions and types of ends

To the cap is attached to the rope holding the submersible pump. Through cap pass the power cable of the pump itself and the discharge pipe.

A tip for wells

A tip for wells is a kind of cover that covers a part of the casing

Installation tip on the hole allows you to realize several objectives:

  • reliable hermetic isolation of the wellhead from a massive snowmelt and flooding;
  • protection of the water supply system from ingress of foreign objects and surface groundwater;
  • reduction in the likelihood of theft of materials and equipment and the well bore;
  • the increase in debit shallow sand wells by forming voltage during operation of the pump;
  • the confrontation between internal freezing part well in the winter months;
  • potable water protection from rain, dirt, dust and debris;
  • the increase in reliability of the suspension of the pump;
  • to simplify the operation of the structure as a whole.
Variety of extension arms to the well

There are several types of heads for wells that differ in the material and workmanship of products

The most in demand and popular among the masses of job seekers remain extension arms for wells, made of plastic, steel or cast iron. For arrangement of shallow wells often used a plastic version of the product.

Construction and installation tip for wells

Device tip for wells equipped with: protective cover, a plastic or metal flange, a rubber ring, fasteners and carbine. On the outside of the metal caps are welded two eye-bolts, and the inner – one.

The main advantages of the installation design — installation of top of the wells does not require welding. The installation is performed by tightening with screws. They compress between a clamping flange and the lid and also layer, made of a sealing rubber ring.

The ease of installation also consists in the possibility of immersion of the pump at the eyebolts, placed on the lid of the product, with lifting devices (crane, hoist).

The attachment of the carabiner to the inside of the cover

At the base of the eyebolt from the inside of the cover fixed the rope, which by means of a carabiner is attached to the pump, which greatly simplifies the operation of water supply system

When building the head first, perpendicular to the axis of the trim casing. The edge of the cut must be straight, cleaned of burrs. The outer surface of the pipe is cleaned, primed and covered with a layer of anticorrosive paint.

After that, the pump can be attached to a plastic tube there to attach the cable to the necessary length and increase cable. The whole construction is tightened with a clamp. The free end of the cable should be attached through the bottom eye-bolt the cover to the carabiner. Advance through the lid to skip the cable and the plastic pressure pipe. The flat surface of the outward flange and a rubber ring is put on the casing.

Lowering the submersible pump into the well, you can set the lid of the dock. To do this you must slightly lift the flange and rubber ring to the level of the cap tip. Flange and cover are tightened together by bolts, while compressed rubber ring, placed between them. To tighten and prevent sagging of pressure polyethylene pipes will help use for fixing collet. Using cable glands you can fix sagging cables.

How to build everything yourself?

For the manufacture of the flange of the cap will need sheet metal in 10mm. Starting from the outer size of the casing should be cut flange, an inner diameter should be slightly greater than this size. According to the flange size should be cut and the plug, which will be subsequently welded introductory fitting for cables and pressurized water system.

Headroom with their hands

Simple product design allows also fast enough to make headroom for the well with their hands

To the outer surface of cap it is necessary to weld two eye-bolts that will be needed for the descent of the pump and lift cover on preventive measures. To the inner surface of the lid should be welded eye-bolt required for mounting on the cable of the pump. Connected to the flange cover is tightened by bolts. Posting under the flange of the rubber ring, it is possible to provide high-quality sealing of the entire structure.
